PHYSICAL STATE; APPEARANCE:
ODOURLESS, WHITE SOLID IN VARIOUS FORMS.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating to high temperature producing carbon dioxide. Reacts with acids causing carbon dioxide release.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV: ppm; 10 mg/m3 Nuisance particulate (ACGIH 1990-1991).


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, by ingestion, and eye contact.

INHALATION RISK:
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes and the respiratory tract.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
See Notes.
PHYSICAL
PROPERTIES
 Melting point (decomposes): 825°C
Relative density (water = 1): 2.7-2.9
 Solubility in water: none
ENVIRONMENTAL
DATA
NOTES
To date, no adverse health effects have been reported. Exists in nature as the minerals aragonite, calcite, vaterite. Limestone, chalk and marble are natural calcium carbonate.
